AWS-RDS-MYSQL-backup-configuration-enable

Severity: High

Description: This control ensures that Native Backup (SQLSERVER_BACKUP_RESTORE) option is configured for MSSQL Instances. Backups provide capability to return to a known safe state in case of any failures. In production environments, maintaining the availability of the data is of paramount importance. To support database operations like recovery and rollbacks in MS SQL databases, native backup is used. Copies of databases can be made for various scenarios such as development, testing and demonstrations using the native backups.
